Specification of Letters Patent.

Application filed May 23, 1912.

Patented June 17, 191 3.

Serial No. 699,294..

To all whom it may concern:

Be it known that I, JOHN D. AIMANN, a citizen of the United States,residing at Stillwater, in the county of Washington and State ofMinnesota, have invented certain new and useful Improvements in JointedTongues and Trucks, of which the following is a specification, referencebeing had to the accompanying drawings.

My invention relates to new and useful improvements in a jointed tongueand truck and has for its object to provide a simple and efficientdevice of this character with improved means for securing the tongue tothe truck proper.

A further object of the invention resides in providing means whereby thetongue may be quickly and readily applied to use and which may bereadily removed, should the occasion require such removal and stillanother object resides in providing a device which is extremely simpleand durable in construction and one which will be very efficient anduseful in operation.

WVith these and other objects in view, the invention consists in thenovel features of construction, combination and arrangement of parts aswill be hereinafter referred to and more particularly pointed out in thespecification and claim.

In the accompanying drawing forming a part of this application, Figure 1is a side elevation of my device applied to use. Fig. 2 is a top planview thereof; and Fig. 3 is a vertical transverse section as seen online 3-3, Fig. 1.

In describing my invention, I shall refer to the drawing in whichsimilar reference characters designate corresponding parts throughoutthe several views and in which 1 indicates the main beam or the like ofthe binder truck, the outer end of which has counter-sunk in the upperand lower faces thereof the plates or strips 2 which are held inposition by means of the bolts 3 and also secured to the upper face ofthe truck beam 1, adjacent the outer end thereof is the plate or strip 4which is bent upwardly to be spaced from the top face of said beam 1 andhave a spring action with respect thereto. A pin or bolt 5 extendsthrough an opening in the outer end of the spring plate 4 and alsoextends through a channel 6 disposed vertically through the beam 1,whereby a draft bar or double-tree may obviously be held on the member1.

An inverted U-shaped member 6 forming a substantial bolster for thedevice has the lower portion thereof curved or bent as shown at 7 androtatably mounted between the free ends thereof is a supporting wheel 8.Formed between the arms of the member 6 and below the horizontal portionthereof is a bridge piece 9 and extending through said horizontalportion is a stud or the like 10, the lower portion of which is reducedand extended through the bridge piece 9. A key or the like 11 extendingthrough the reduced portion of the stud 1O securely retains the latteron the member 6 and the projecting portion of the stud 10 is extendedthrough a vertical channel 12 formed in the member 1 adjacent the freeend thereof. That portion of the stud 10 which extends above the beam 1,after passing through the channel 12, has encircled thereon a collar 13and a set screw 14 extending through said collar is adapted to beengaged with the stud, whereby it will be appreciated that the member 6may be removably held to the truck.

In order to secure a tongue or pole 15 to the beam 1 of the truck, apair of straps or arms 16 are provided and secured to the side faces ofthe beam 1, by means of the bolts 17, said arms 16 having portionsthereof bent outwardly in opposite directions from the beam 1. The freeends of these arms or straps 16 which terminate in a line with the endof the beam 1 are forked or bifurcated, as shown at 18, the furcationsthereof being provided with alining openings. The inner end of thetongue 15 is also provided with a pair of straps or arms 19 which aresecured to the side faces thereof by means of the bolts 20 and portionsof these arms 19 are also bent outwardly in opposite direc tions fromthe tongue so that the free ends thereof may be readily entered betweenthe furcations of the outer ends of the arms 16. The free ends of thesearms 19 are also provided with openings which are adapted to aline withthe outer ends of said arms 16 and when so positioned for alinement, abolt 21 is extended therethrough and the free end thereof engaged with anut 22. In disposing this bolt through the arms 16 and 19, the same isalso disposed through a channel adjacent the outer end of the beam 1 anddisposed on said bolt between the beam 1 and the bifurcated ends of thearms 16 are the collars 23. A. bracing strip 24 is also provided andsecured by means of a screw or the like 25 to the inner end of thetongue 15, the ends of said strip being bent and secured to the arms 19adjacent the free ends thereof.

From the foregoing description of the construction of my device, theoperation thereof will be readily understood and it will be seen that Ihave provided a simple and durable tongue truck which is inexpensive tomanufacture and one which will be very eflicient and useful inoperation.

While I have particularly described the elements best adapted to performthe functions set forth, it is obvious that various changes in form,proportion and in the minor details of construction may be resorted towithout departing from the spirit or sacrificing any of the principlesof the invention.

Having thus described this invention, what I claim is In a tongue truck,the combination with a beam, a supporting wheel rotatably supportedbelow said beam, a pair of straps secured to the sides of said beam andflared outwardly, the outer free ends of said straps being bifurcatedand extended to the plane of the outer end of said beam; of a tongue, apair of additional straps secured to the sides thereof and also flaredoutwardly, the free ends of said additional straps being eX- tended to aplane beyond the inner end of said tongue and disposed respectively inthe bifurcated ends of the first mentioned straps to space the outer endof said beam and the inner end of the tongue from one another, a bracingstrap secured to the inner end of said tongue and engaged with saidadditional straps, a bolt extended through the free ends of said firstmentioned and additional straps and also through said beam to pivotallysecure said tongue to the beam, collars disposed on said bolt betweenthe bifurcated ends of the first mentioned straps and the sides of saidbeam, and means engaged with said bolt to secure the latter and saidcollars in position.

In testimony whereof I hereunto affix my signature in the presence oftwo Witnesses.
